520nm laser pointer powered by AAA?

This illustrates an issue you may have.

Sure, they are not simple drop in replacemets, but there are plenty of flashlight hosts that actually run off a 3-AAA arrangement like that by default and could be used to house a laser pointer.

They will obviously not fit a bore designed to take an 18650 cell specifically. They will fit 25650 hosts with a spacer and a bit of rattle, but probably not provide the current required anything of serious power output.
